Question details

Comparison Instructions, Data Conversion, and Analog Scaling

I'm a new user of ABB PLC's and Codesys, I'm trying to write a program using Ladder Logic, and I need to compare values. Every other PLC I've ever worked with has had Equal to, Greater than, etc instructions, are these not available with these PLC's? Same with Analog Scaling and Data conversion blocks. Are these available?

Thanks, I figured it out shortly after I posted the question. The other thing I'm having issues with is addressing data to the %M area for access to an HMI via modbus, I keep getting told its not a valid address, is there someway to set this area up?
